Hi, 
 
	I'm facing no/Black color issue with my Heatmap. 
 
	I've created a heatmap. Say dimension is Month and the values are all zero, I gave minvalue=0, maxvalue=100, color range 0 to 50 is 'Red', 50 to 100 is 'Green'. 
 
	When I have only zero values for all months I get color as Black but when any value is more than 0 for any of the Month, all the other zero values starts showing 'Red' as expected. 
 
	I need to know why the color is Black when all values are Zero, I need 'Red' for all the months even if all values are 0. Why it is not considering minValue as 0.
 
	Please suggest. 
 
	Thanks
